Warnings
This device complies with part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
Caution: Any changes or modifications by the user could void the user’s authority to
operate the equipment!
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate frequency energy and, if not installed in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Operation Description TC690
The TC690 consists of an integrated transceiver, voltage regulator, undervoltage reset
circuit and microcontroller. The receiver part is a single conversion superhet. The local
oscillator is a dds type with pll multiplier (see block diagram).
The module is supplied via pins 1~4 (+3.3~4.7V) and pins 11, 12, 27 & 28 (ground). For
correct operation, pin 15 has to be connected to pin 16. Also, pin 23 has to be connected
to pin 24. The module will be switched on by driving pin 9 (DTR) to low level.
The voltage of the SPI interface may not exceed 3.3V! The logic level shall be in the
range 2.3~3.0V for a logical ’1’ and 0~0.7V for a logical ’0’.
When user data is applied to the SPI interface (pins5~8), the data will be transmitted
automatically. When correct data is received, it will be sent through SPI interface.
Frequency programming will be done by applying configuration data to the SPI interface.
In all cases, the microcontroller software checks for correct data format. It is not possible
to transmit outside the programmed frequency range. Since the RF data rate is
independent of the SPI data rate, it is not possible to overmodulate the transmitter. Also,
the transmitting time is limited by software.
